Briefly, 2,4-dichloropyrimidine (1) was reacted with 3-amino-9-ethylcarbazole (2) by heating in iso-propanol in the presence of N,N-diisopropylethylamine. Separation of the regioisomers provided the pure 4-substituted pyrimidine derivative (3), which was reacted with 4-(3-Aminopropyl)morpholine (4) in sec-butanol under microwave heating in the presence of N,N-diisopropylethylamine to provide EHop-016 (5).
